Mutalk reduces speech volume by -20 decibels and even by -30 decibels for louder noises. Shiftall claims people sitting right next to you can't hear what you're saying wearing the device. The cushion that you’ll be spitting into is washable.
The developers promise over 10 hours of battery life. Mutalk is compatible with Windows, macOS, iOS, and Android.
